Medicine Balls
Medicine balls are not meant for slamming unlike dead balls but are a great tool for upper body and core strengthening movements. You can use them for individual or partner workouts that will raise your heart rate for that extra cardio burn. Think about throwing to your partner, throwing at a wall and in the air, catching, gripping and squatting, running with them. They are purposefully awkward and ideal for functional training to throw you off balance which will test smaller stabilising muscle groups as well as larger power muscles.
